Specification of Letters Patent;

Patented Jan. 30, 1912.

Application filed November 1, 1911. Serial No. 658,052.

To (ZZZ whom it may concern Be it known that I, FREDERIGK MILLER, a citizen of the United States of America, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a certain new and useful Roundabout; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to roundabouts, and it may be said to consist in the provision of the novel features and in the novel and improved construction, arrangement and combination of parts and devices therein as will be apparent from the description and claims which follow.

One object of the invention is to provide novel and improved means for imparting motion to and controlling the movement of the conveyances of the roundabout.

Further objects of the invention are to provide for a roundabout of a novel and improved construction which is simple in character, economical to install and maintain, easy and economical to operate, effective in action, and which is practical and produces results which make it superior to existing construction of like nature.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a consideration of the following description of the preferred form of construction embodying the invention, taken in connection with the accompanying drawings in which Figure 1 is a view taken on the line 11 of Fig. 2; Fig. 2 is a view taken on the line 22 of Fig. 1; Fig. 3 is a partially broken detail view of the grooved member on the uprights, and Fig. 4 is a conventional plan view of a portion of the roundabout.

A suitable structure 2 may be formed to provide an endless guideway 3, the latter preferably being made circular as seen in Fig, 4. To the framework of any suitable form of conveyances 4 may be secured-the uprights 5 having mounted at the free end thereof the large rollers 6 which are adapted to bear against a wear resisting strip 7 in the guideway 3. As shown, an uprlght 5 may be arranged substantially centrally at each end of the conveyances 4, and so may also the oppositely disposed rollers 8 which are connected with the framework of the conveyances and adapted to bear against the wear resisting strips 9 in the guideway 3. The conveyances 4 may be connected to gether to travel at a substantially constant distance apart by a cable 10 which may be held to the uprights 5 by means of lugs 11 on the uprights. The cable 10 between adjacent conveyances may move in one of the grooves of the double-grooved sheaves 12 which are mounted adjacent to the guideway 3 and extend into the guideway and have their outer extremity in close proximity to the lugs 11. A turnbuckle 13 and spring 14 are preferably arranged adjacent to the conveyances 4 and joined to the cable 10 to prevent sudden change of motion of the cable 10 being transmitted to the conveyances. On the outer side of the uprights 5 may be affixed curved grooved members 15 and an endless cable 16 may pass through the grooved members 15 and around the driving pulley indicated at 17; the portions of the cable 16 between adjacent conveyances moving in one of the grooves of sheaves 12. As shown in Fig. 4, the cable 16 is preferably guided to the driving pulley 17 by passing on opposite sides of a double grooved sheave indicated at 18.

From the foregoing the mode of operation will be readily understood, it being seen that the cable 16 is directly driven and transmits motion to the sheaves 12 to have the latter transmit mot-ion to the cable 10. The conveyances are operatively connected with both cables 10 and 16 to be continuously driven by the cables and to travel at a substantially constant distance apart.

While one form of construction in which the invention may be embodied has been illustrated and described, many changes-and modifications thereof will readily occur to those skilled in the art, wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. In a roundabout, the combination of an endless guideway, conveyances arranged adjacent to said guideway, guides disposed in the guideway and connected with the conveyances, a cable connecting said conveyances together, grooved members carried by and extending longitudinally of the conveyances, a driving pulley, and an endless cable passing through said grooved members and around said pulley, substantially as described.

2. In a roundabout, the combination of an endless guideway, conveyances arranged adjacent to said guideway, rollers disposed in the guideway and connected with the c0nveyances, grooved members carried by and extending longitudinally of the conveyances, a driving pulley, an endless cable passing through said grooved members and around said pulley, and means to cause said conveyances to travel at a substantially constant distance apart, substantially as described.

3. In a roundabout, the combination of an endless guideway, conveyances arranged ad jacent to said guideway, guides disposed in the guideway and connected with the conveyances, a cable connecting said conveyances together, means carried by said conveyanees for connecting with said cables, grooved members carried by and extending longitudinally of said conveyances, a driving pulley, an endless cable passing through said grooved members and around said pulley, and sheaves for the cables, substantially as described.

4:. In a roundabout, the combination of an endless guideway, conveyances arranged adjacent to said guideway, uprights carried by said conveyances, guides disposed in the guideway and connected with the conveyances, a cable extending between the conveyances and connected with said uprights, a spring and turnbuckle arranged adjacent to the conveyances and joined to said cable, grooved members carried by said conveyances, a driving pulley, an endless cable passing through said grooved members and around said pulley, and sheaves for the cables, substantially as described.

5. In a roundabout, the combination of an endless guideway, conveyances arranged adjacent to said guideway, uprights carried by. said conveyances, rollers disposed in the guideway and connected with the conveyances and with the uprights, a cable connecting said conveyances together, grooved members carried by and extending longitudinally of said conveyances, a driving pulley, an endless cable passing through said grooved members and around said pulley, and sheaves for the cables, substantially as described.

6. In a roundabout, the combination of an endless guideway, conveyances arranged adjacent to said guideway, uprights carried by said conveyances, rollers disposed in the guideway and connected with the conveyances and with the uprights, cables eXtending between the conveyances and connected with said uprights, a turnbuckle and a spring arranged adjacent to the conveyances and joined to said cables, grooved members atlixed on the outer side of said uprights, a driving pulley, an endless cable passing through said grooved members and around said pulley, and double grooved sheaves for the cables, substantially as described. 1

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses at Los Angeles, county of Los Angeles, State of California, this 24th day of October A. D. 1911.
